0005  *
0006  *  Class to store a list of index functions.
0007  *
0008  *  A counter is a pointer to a function that returns the number of an
0009  *  alignable based on its id.
0010  *  The number of an alignable is given by its position within its parent.
0011  *  User gets a counter using its structure type via AlignableIndexer::get(type).
0012  *  Each sub-system has its own concrete counter class implementation.
